Functions

func B64Decode 

func B64Decode(str string) (buf []byte, err error)

B64Decode base64 decodes a string

func B64Encode

func CreateToken 

func CreateToken(cert []byte, key []byte, body []byte) (string, error)

CreateToken creates a JWT-like token. In a normal JWT token, the format of the token created is: 

<algorithm,claims,signature>

where each part is base64-encoded string separated by a period. In this JWT-like token, there are two differences:

  1. the claims section is a certificate, so the format is: <certificate,signature>
  2. the signature uses the private key associated with the certificate, and the signature is across both the certificate and the "body" argument, which is the body of an HTTP request, though could be any arbitrary bytes.

@param cert The pem-encoded certificate @param key The pem-encoded key @param body The body of an HTTP request
